When rubber belt track 92 rotates, and the rake 74 of anti-tensile body 70 moves from straight section F towards bent portion C
When, as shown in Figure 2 B, rake 84 tilts from crawler belt outer circumferential side towards inner circumferential side.Therefore, the crawler width direction of anti-tensile body 70
End is significantly moved towards crawler belt inner circumferential side, and anti-tensile body 70 makes rubber belt track main body 12 towards crawler belt inner circumferential side flexing.This
In, each rake 84 is 2.5 ° to 5.8 ° relative to the maximum tilt angle in crawler width direction towards crawler belt inner circumferential side.Knot
Fruit, in each wheel rolling face 40 positioned at the inner circumferential side of rubber belt track main body 12, positioned at the flat of crawler width direction center side
Inclined plane 44 is formed on the outside of the crawler width direction in smooth face 42.Here, the inclined plane 44 in each wheel rolling face 40 is towards in crawler belt
The week side of boss is 2.5 ° to 7.5 ° relative to the maximum tilt angle in crawler width direction.Inclined plane 44 and driving wheel 100 or idle whee
102 contacts.
If rubber belt track 92 starts snakelike movement, driving wheel 100 and idle whee 102 are relative to rubber belt track main body 12
The relative position on crawler width direction stagger.Thus, driving wheel 100 and idle whee 102 are pressed against and formed in rubber
The inclined plane 44 of the side on crawler width direction of the inner peripheral surface of track body 12.Therefore, outside the crawler belt of inclined plane 44
The elastomer backup anti-tensile body 70 of the week side of boss, the result is that being generated in the anti-tensile body 70 of the side on crawler width direction
Tension force, and Tension Difference is generated between the outside of the side on the inside of the width of rubber belt track main body 12.Therefore, rubber
Glue track body 12 is towards the side movement on the higher crawler width direction of tension force, to eliminate the tension force in anti-tensile body 70
Difference.As a result, the width of the relative position at the crawler width direction center of driving wheel 100 and idle whee 102 and rubber belt track main body 12
Spend direction center alignment.Therefore, it is possible to suppress the snakelike movement of rubber belt track 92.In addition, because inhibit rubber belt track 90
Snakelike movement, so having relaxed scroll wheel 104 with forming the guide protrusion 16 in the width central portion of rubber belt track 90
Contact between side, guide protrusion 16 is caused to damage so as to inhibit.
The outside inclined height L5 of each rake 74 in straight section F of anti-tensile body 70 can be set to that driving wheel
The 0.35% of the distance between 100 rotation axis O1 and the rotation axis O2 of idle whee 102 L7 (axle wire spacing).As a result,
Each rake 74 contacted with driving wheel 100 or idle whee 102 in the C of bent portion forms following structure：The structure has
It is enough the inner side inclined height L6 (rakes in the C of bent portion for pushing back the center of guide protrusion 16 towards scroll wheel 104
The distance between 74 crawler width direction outboard end and flat part).
Although inclined height L5 is set to the 0.35% of axle wire spacing L7 in this illustrative embodiments China and foreign countries side,
It is the construction not limited to this of the present invention.It is sufficient that outside inclined height L5 is more than the 0.3% of axle wire spacing L7.It is if outer
Side inclined height L5 is less than the 0.1% of axle wire spacing L7, then is contacted in the C of bent portion with driving wheel 100 or idle whee 102
Rake 74 can not be formed with the inner side inclined height for being enough to push back in the center of guide protrusion 16 towards scroll wheel 104
Structure, so as to make the effect of 90 snakelike movement of suppression rubber belt track die down.
In straight section F, because scroll wheel 104 rolls on the wheel rolling face 40 parallel with crawler width direction
It is dynamic, so compared with being the crawler belt of inclined plane with whole wheel rolling face, it can relax from scroll wheel 104 and be applied to crawler belt inner circumferential
The local force in face.Therefore, it is suppressed that crawler belt inner peripheral surface is caused to damage.
During the traveling of caterpillar, when rubber belt track 92 is wrapped on driving wheel 100 and idle whee 102, position
Crawler belt inner circumferential side is pulled to by the rake 74 of anti-tensile body 70 in the end of the projection 18 of crawler belt outer circumferential side.As a result, the direction of projection 18
Move crawler belt inner circumferential side.Come off therefore, it is possible to make to hang over the dust on projection 18, stone etc..
